Releases: sourcefrog/cargo-mutants
cargo-mutants 23.5.0
"Pickled crab"
-
cargo mutants
can now successfully test packages that transitively depend on a different version of themselves, such asitertools
. Previously, cargo-mutants used the cargo--package
option, which is ambiguous in this case, and now it uses--manifest-path
instead. #117 -
Mutate functions returning
&'_ str
(whether a lifetime is named or not) to return"xyzzy"
and""
. -
Switch to CalVer numbering.
cargo-mutants 1.2.3
-
New
--error
option, to cause functions returningResult
to be mutated to return the specified error. -
New
--no-config
option, to disable reading.cargo/mutants.toml
. -
Mutate functions returning
String
toString::new()
rather than"".into()
: same result but a bit more idiomatic. -
New
--leak-dirs
option, for debugging cargo-mutants. -
Update to syn 2.0, adding support for new Rust syntax.
-
Minimum supported Rust version increased to 1.65 due to changes in dependencies.
cargo-mutants-1.2.2
-
Don't mutate
unsafe
fns. -
Don't mutate functions that never return (i.e.
-> !
). -
Minimum supported Rust version increased to 1.64 due to changes in dependencies.
-
Some command-line options can now also be configured through environment variables:
CARGO_MUTANTS_JOBS
,CARGO_MUTANTS_TRACE_LEVEL
. -
New command line option
--minimum-test-timeout
and config file variableminimum_test_timeout
join existing environment variableCARGO_MUTANTS_MINIMUM_TEST_TIMEOUT
, to allow boosting the minimum, especially for test environments with poor or uneven throughput. -
Changed: Renamed fields in
outcomes.json
fromcargo_result
toprocess_status
and fromcommand
toargv
. -
Warn if no mutants were generated or if all mutants were unviable.
cargo-mutants-1.2.1
-
Converted most of the docs to a book available at https://mutants.rs/.
-
Fixed: Correctly find submodules that don't use
mod.rs
naming, e.g. when descending fromsrc/foo.rs
tosrc/foo/bar.rs
. Also handle module names that are raw identifiers usingr#
. (Thanks to @kpreid for the report.)
cargo-mutants 1.2.0
Thankful mutants!
-
Fixed: Files that are excluded by filters are also excluded from
--list-files
. -
Fixed:
--exclude-re
and--re
can match against the return type as shown in--list
. -
New: A
.cargo/mutants.toml
file can be used to configure standard filters and cargo args for a project.
cargo-mutants 1.1.1
Spooky mutants!
-
Fixed support for the Mold linker, or for other options passed via
RUSTFLAGS
orCARGO_ENCODED_RUSTFLAGS
. (See the instructions in README.md). -
Source trees are walked by following
mod
statements rather than globbing the directory. This is more correct if there are files that are not referenced bymod
statements. Once attributes on modules are stable in Rust (rust-lang/rust#54727) this opens a path to skip mods using attributes.
cargo-mutants-1.1.0
Fearless concurrency!
-
cargo-mutants can now run multiple cargo build and test tasks in parallel, to make better use of machine resources and find mutants faster, controlled by
--jobs
. -
The minimum Rust version to build cargo-mutants is now 1.63.0. It can still be used to test code under older toolchains.
cargo-mutants-1.0.3
-
cargo-mutants is now finds no uncaught mutants in itself! Various tests were added and improved, particularly around handling timeouts.
-
New:
--re
and--exclude-re
options to filter by mutant name, including the path. The regexps match against the strings printed by--list
.
cargo-mutants-1.0.2
-
New:
cargo mutants --completions
to generate shell completions usingclap_complete
. -
Changed:
carg-mutants
no longer builds in the source directory, and no longer copies thetarget/
directory to the scratch directory. Sincecargo-mutants
now setsRUSTFLAGS
to avoid false failures from warnings, it is unlikely to match the existing build products in the source directorytarget/
, and in fact building there is just likely to cause rebuilds in the source. The behavior now is as if--no-copy-target
was always passed. That option is still accepted, but it has no effect. -
Changed:
cargo-mutants
finds all possible mutations before doing the baseline test, so that you can see earlier how many there will be. -
New: Set
INSTA_UPDATE=no
so that tests that use the Insta library don't write updates back into the source directory, and so don't falsely pass.
cargo-mutants 1.0.1
-
Fixed: Don't try to mutate functions within test targets, e.g. within
tests/**/*.rs
. -
New:
missed.txt
,caught.txt
,timeout.txt
andunviable.txt
files are written in to the output directory to make results easier to review later. -
New:
--output
creates the specified directory if it does not exist. -
Internal: Switched from Argh to Clap for command-line parsing. There may be some small changes in CLI behavior and help formatting.
